Your dad, your driving instructor, and the smelly people you turn to for advice on Yahoo Answers all told you to put your hands at "10 & two" (referring to those two numbers' positions on the clock) while driving. We're not sure where this initially came from, but it's wrong.
Every car control expert in the world, from the Hollywood stunt man to Sebastien Vettel drives with his or her hands at nine and three because it gives the driver more freedom of movement, more precision, and better reflexes. F1 steering wheels don't even have a place to grab the wheel anywhere else at this point. The added bonus is that if your airbag goes off, you won't Hulk smash your own face with the power of a small explosive.
